Expanding on Electro-Harmonix’s first homage to the tone that launched a thousand riffs, the Electro-Harmonix Satisfaction Plus fuzz effects pedal delivers a wide palette of tones — from classic ’60s snarl to creamy lead tone and thick, earth-shaking sludge.

Where the original Satisfaction Fuzz circuit was a focused tribute, the EHX Satisfaction Plus Fuzz treats the classic tone to an enhanced, modern control set that includes a FAT/NORM mode switch, bias control, and Tone knob. The added FAT mode features a tone that is bigger and warmer than the NORM mode for woolly leads and giant wall-of-thunder riffs. The Tone control is an active tilt-shift EQ, which inversely controls both the treble and bass of the fuzz for broad tonal shifting. Set the Bias control to dial in the fuzz character from balanced and open to gated and snarly.
